    摘要： A light modulating device is disclosed herein. In some embodiments, a light modulating device includes a first substrate having a first surface, a pressure-sensitive adhesive layer or an adhesive layer formed on the first surface of the first substrate, a second substrate, a liquid crystal layer disposed between the first and second substrates; and a partition wall spacer, wherein the partition wall spacer maintains a distance between the first and second substrates, wherein the liquid crystal layer is capable of being configured in a twist orientation, and wherein a ratio of thickness of the liquid crystal layer relative to a pitch of the liquid crystal layer in the twist orientation is more than 2.8 and 10 or less. The light modulating device can have a wide transmittance variable range and does not have problems, such as liquid crystal defects or visibility deterioration, while implementing low transmittance in a black mode.

    摘要： An optical device is disclosed herein. In some embodiments, an optical device includes a first outer substrate, a second outer substrate, a liquid crystal element film positioned between the first and second outer substrates, intermediate layers positioned between the first outer substrate and the liquid crystal element film and between the liquid crystal element film and the second outer substrate, respectively, wherein a sum of the total thicknesses of the intermediate layers is 1,600 μm or more. The optical device can secure structural stability and good quality uniformity by maintaining the cell gap of the liquid crystal element film properly, having excellent attachment force between the upper substrate and the lower substrate, and minimizing defects such as pressing or crowding in the bonding process of the outer substrates.

    摘要： A light modulation element that can vary between a bright transparent mode and a dark scattering mode is provided. The light modulation element has a first light modulation layer and a second light modulation layer comprising nematic liquid crystals and a dichroic dye in a scattering mode when a voltage is applied. The first light modulation layer and the second light modulation layer are disposed to overlap each other. The light modulation element has an improved contrast ratio and haze-variable characteristics, without precipitation of dichroic dyes and an increase in power consumption.
